Quantification of steroid hormones in free‐ranging Apennine wolf Canis lupus italicus hair samples collected post‐mortem

open access: yesWildlife Biology, EarlyView.
After decades of dramatic reductions in their populations, Italian wolves have begun recolonizing parts of their historic range. This growth in populations can lead to potential conflicts with human activities, which remain the main cause of wolf mortality.

NaSC2H: A First Crystalline Compound with a −SC2H Anion, an Isolobal Variant of Ubiquitous −SCN

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
Crystalline NaSC2H was obtained by reacting NaC2H with elemental sulfur in liquid ammonia. It contains −SC2H anions, which was confirmed by infrared and Raman spectroscopy as well as by structural elucidation based on synchrotron powder diffraction data. −SC2H is a new isolobal variant of the ubiquitous −SCN anion (thiocyanate).

Liquid Scintillation Counting

open access: yes, 1993
In liquid scintillation counting (LSC) we use the process of luminescense to detect ionising radiation emit$ed from a radionuclide. Luminescense is emission of visible light of nonthermal origin. 1t was early found that certain organic molecules have luminescent properties and such molecules are used in LSC.

Cold versus thermal neutron source: assessment of performance of the KWS‐2 SANS diffractometer of the Jülich Centre for Neutron Science at the FRM II reactor

open access: yesJournal of Applied Crystallography, EarlyView.
The performance of the small‐angle neutron scattering (SANS) diffractometer KWS‐2 is evaluated by measurements and McStas simulations under the condition that only the thermal neutron source is available at the FRM II reactor. This is compared with the established performance with cold neutrons provided by the cold neutron source.The small‐angle ...

Increased ATP production and P‐glycoprotein activity underlie the marked changes in blood–brain barrier transport of drugs in a mouse model of amyotrophic lateral sclerosis

open access: yesBritish Journal of Pharmacology, EarlyView.
Background and purpose Patients with amyotrophic lateral sclerosis (ALS) are prescribed many medications for symptomatic relief. However, how potential alterations to the blood–brain barrier (BBB) affect the brain exposure of drugs in ALS remains under‐investigated. Experimental approach We used high‐dimensional proteomic analysis, cellular metabolism,

Gαs‐specific structural elements attenuate interactions with regulator of G protein signaling (RGS) proteins

open access: yesThe FEBS Journal, EarlyView.
Heterotrimeric (αβγ) G proteins are usually inactivated by regulators of G protein signaling (RGS) proteins, but Gαs is an exception. Comparative structural analysis identified unique Gαs structural elements that may interfere with RGS binding. Mutagenesis and biochemical assays showed that three residues in the Gαs GTPase domain are both necessary and
